Parker PT-00788 Flareless Bite-type Tube Plug 12mm

Product Description

The PARKER PT-00788 is a flareless bite-type tube plug designed to seal hydraulic and instrumentation tubing lines without requiring a flared tube end. The plug accepts a 12 mm outside diameter tube and uses the bite-type ferrule design to grip and seal against the tube wall. This fitting is suited for capping open tube ends in fluid power systems, pneumatic circuits, and instrumentation lines during service, testing, or permanent decommissioning. Licensed plumbers, hydraulic technicians, and instrumentation fitters typically install this type of plug where a leak-free cap is required on a flareless metric tube assembly.

This tube plug is intended for use in metric tube systems where the bite-type compression fitting standard applies. Typical applications include capping unused ports in hydraulic manifolds, sealing instrument lines during maintenance, and blanking off branch connections in pneumatic distribution systems. It is compatible with 12 mm OD tubing used in industrial, HVAC, and fluid power installations. The plug ships in package quantities of five, making it practical for service kits and field stock.

Key Features

• Flareless bite-type design eliminates the need for tube flaring before installation
• 12 mm tube OD sizing for metric tubing systems
• Seals open tube ends in hydraulic, pneumatic, and instrumentation circuits
• Compact plug form factor suitable for confined manifold and panel installations
• Sold in packs of five to support field service and preventive maintenance stock

Compatibility

Designed as an OEM-style replacement and service fitting for flareless bite-type metric tube assemblies using 12 mm outside diameter tubing.

Installation Notes

Installation is typically performed by hydraulic technicians or instrumentation fitters. Depressurize and isolate the fluid or pneumatic line fully before removing any fitting or installing this plug. Follow the fitting manufacturer torque procedure for bite-type fittings, which generally involves a defined number of turns past hand-tight to seat the ferrule. Do not reuse a ferrule that has already been swaged onto a tube, as the bite-type seal depends on the initial ferrule deformation.
